// We MUST return an iq, whatever happens, except if the type is

// To do this, we use a scopeguard. If an exception is raised somewhere, an
// iq of type error "internal-server-error" is sent. If we handle the
// request properly (by calling a function that registers an iq to be sent
// later, or that directly sends an iq), we disable the ScopeGuard. If we
// reach the end of the function without having disabled the scopeguard, we
// send a "feature-not-implemented" iq as a result. If an other kind of
// error is found (for example the feature is implemented in biboumi, but
// the request is missing some attribute) we can just change the values of
// error_type and error_name and return from the function (without disabling
// the scopeguard); an iq error will be sent
